The Cardiovascular System Is Made Up Of 3 Things

Both the right and left atrium contract causing blood to flow though the two valves, and then into the left ventricle. The left ventricle pumps blood into the systemic circulation through the aorta. This systemic circulation system is much bigger than the pulmonary circulation system, which is why the left ventricle is so big. The blood on the left side of the heart is oxygenated. It becomes oxygenated when the deoxygenated blood passes through the right atrium and then flows into the left ventricle. It is then pumped along the pulmonary artery into the lungs where it is oxygenated. It then travels through the pulmonary veins back into the heart. It enters through the left atrium and then travels to the left ventricle. This process is repeated over and over again, to make blood continuously flow through the heart, lungs and body. This process ensures that there is always enough oxygen for the body to work

The cardiovascular system, however, would not be able to effectively complete these functions without help from what is sometimes referred to as the body’s hardest-working organ- the heart. Approximately the size of a fist, the heart is contains four chambers (the uppermost are called the atria and the lowermost are called the ventricles) and four valves. Additionally, the heart is surrounded by the pericardium, a structure that serves to protect the heart, keep the heart stabilized in the chest, and

In a normal human being the heart correctly functions by the blood first entering through the right atrium from the superior and inferior vena cava. This blood flow continues through the right atrioventricular valve into the right ventricle. The right ventricle contracts forcing the pulmonary valve to open leading blood flow through the pulmonary valve and into the pulmonary trunk. Blood is then distributed from the right and left pulmonary arteries to the lungs, where carbon dioxide is unloaded and oxygen is loaded into the blood. The blood is returned from the lungs to the left

Pulmonary circulation transports deoxygenated blood from the right side of the heart to the lungs where the blood picks up oxygen and returns

Blood has many functions and is a complex structure of cells and fluid. It helps fight bacteria, protect the body from infection, carry valuable sources of minerals and nutrients around the body, dispose of waste materials, keeps the body temperature regulated and helps with glandular distribution of hormones and enzymes.

The heart is a very strong muscle that has one major job. The heart’s job is to pump blood throughout the entire body. The heart is made up of 4 chambers, and 4 valves. There is the right and left atrium, and a right and left ventricle. The atriums are the superior chambers, and the ventricles are inferior chambers. The left ventricle is the most important, because that is where the blood travels through to go to the aorta, and eventually the rest of the body (Taylor 2015).

Tim Taylor, 2012) has argued that cardiovascular system referred to as the circulatory system, is composed of blood within the blood vessels and heart. The function of the heart is pumping the blood through the blood vessels of the body.

Blood comes from the Superior and Inferior vena cava, into the right atrium. As the right atrium fills with blood, it contracts and the tricuspid valve opens and the blood pumps into the valve. When the right ventricle is full the tricuspid valve close to ensure blood moves in the right direction. The blood then moves to the right ventricle and into another valve called the Pulmonary valve. Then moves to the pulmonary artery and into the lungs. The blood moves into the lungs and picks up fresh oxygen. Then it returns to the left heart through the pulmonary veins to the left atrium. It passes through the mitral valve and enters the left ventricle. Oxygenated blood moves into the aortic valve and into the Aorta to reach all parts of the body ( heart.org).

The heart is located beneath the rib cage, between the lungs, to the left of the sternum (breastbone). Most people believe that the heart is located on the left side of the chest because the bottom of the heart is tipped to the left. Therefore, you feel more of your heart on the left side. The heart is a powerhouse with muscular walls that contract, thrusting blood throughout the body’s blood vessels. The blood must flow in one direction in order for the heart to function properly. The three focal types of vessels are arteries, capillaries, and veins which form the circulatory system. These vessels, like elastic tubes, transport blood to every portion of the body. Arteries carry oxygen-rich blood away from the heart to all of the body’s tissues. They progressively become smaller as blood is carried further away from the heart. The capillaries are the small, thin blood vessels that connect the arteries to the veins. Nutrients, carbon dioxide and waste products are allowed to pass to and from the tissue cells by their thin walls. Veins, on the other hand, carry the oxygen-poor blood back to the heart. These vessels gradually become larger as they get near to the heart. The blood vessel system runs over 60,000 miles long.

The arteries are branched into smaller arteries, arterioles and capillaries. Carbon dioxide and waste are diffused out of the cell into the blood, while oxygen is diffusing out of the blood into the cell. The deoxygenated blood continues to flow through the capillaries, which more into venules, veins and eventually, the heart. From the right atrium, the blood will go through the pulmonary circulation again.

The system has two functions: to deliver oxygen and nutrients to cell and tissues & to remove carbon dioxide and other waste products from the cells and tissues. The base of the heart points toward the right shoulder, also it is about the size of your fist. The first layer of the heart wall is the epicardium. It is comprised of connective tissue that makes up the visceral pericardium. The middle layer is the myocardium, which is mostly cardiac muscle. The innermost layer is the endocardium. The heart has 4 chambers which allow is the pump correctly. Two atria chambers which receive blood and two ventricular chambers which discard of blood. There are two septa`s in the heart. The interventricular ( separates the 2 ventricles) and the interatrial (separates the 3 atria). Blood circulation is a thing because of the heart. Systemic circulation allows the blood to flow from the left side through the tissues and back to the heart entering on the right side. Pulmonary circulation allows the blood to flow from the right side to the lungs and back entering on the left side. A valve allows the blood to flow in one direction, it prevents backflow. There are 4 valves throughout the heart. They are the atrioventricular valve, bicuspid valve, semilunar valve, and the tricuspid valve. The two most important valves are the AV valve and the semilunar valve. The continuous circulation of blood through the body is vital for

The cardiovascular systems function is to pass blood through ones body keeping their muscles oxygenated, to keep nutrients that are needed in the body and to help get rid of metabolic waste. The cardiovascular system is made up of three components, these are; the heart, the blood and the blood vessels.

The cardiovascular system is the system involved with transporting blood throughout the body. This system consists of three interrelated components: the heart, blood and blood vessels. The heart is the pump that circulates the blood throughout the body. Blood is needed to reach body cells to exchange materials with them. The heart pumps the blood through the body’s blood vessels so that I can reach where it is needed. Blood has two components: blood plasma, a watery liquid containing dissolved substances, and formed elements, which are cell fragments and cells (red blood cells, white blood cells and platelets). Blood contributes to homeostasis by transporting nutrients, carbon dioxide, hormones and oxygen, to and from your body’s cells. It

As the world of technology changes, we get to explore and visually get to see how the heart and the Circulatory system works. “The cardiovascular system consists of the heart and blood vessels circulating blood throughout the body, delivering water, oxygen, and nutrients to cells, and removing waste products such as carbon dioxide blood vessels working together to is system”. (Wiley) And now for the Circulatory system is also a major function of our body, “The basic circulatory system of vertebrate animals, which are those with a backbone, consists of a heart, the blood and the arteries and system of blood vessels. The heart pumps the blood first to the arteries and then throughout the body via the system of blood vessels”. (reference.com)

The human heart has four chambers partitioned by an interventricular septum, two on either sides called right and left. Each side has an atrium that receives blood and a ventricle that pumps the blood. It has two types of circulations, also called systems: the pulmonary heart and the systemic heart. The pulmonary heart, the right side of the heart, pumps blood out to the lungs and the systemic heart, the much thicker left side of the heart, pumps out to all the systems in the body. They are: circulatory-heart, digestive, endocrine, immune, lymphatic, muscular, nervous, reproductive, respiratory, skeletal, and the urinary system.
